An Odd-Even Sort or brick sort is a simple sorting algorithm, which is developed for use on parallel processors with local interconnection. It works by comparing all odd/even indexed pairs of adjacent elements in the list and, if a pair is in the wrong order the elements are switched. The next step ...

You could describe variable affectation in different ways. Typed int a = 1 int a := 1 let int a = 1 int a <- 1 No type a = 1 a := 1 let a = 1 a <- 1

As long as the function name, return statement and parameters are clear, you're fine. def incr n return n + 1 or let incr(n) = n + 1 or function incr (n) return n + 1 are all quite clear, so you may use them. Try not to be ambiguous with a variable affectation

An example implementation of BubbleSort in C++: void bubbleSort(vector<int>numbers) { for(int i = numbers.size() - 1; i >= 0; i--) { for(int j = 1; j <= i; j++) { if(numbers[j-1] > numbers[j]) { swap(numbers[j-1],numbers(...

The BigInteger class has a constructor dedicated to generate random BigIntegers, given an instance of java.util.Random and an int that specifies how many bits will the BigInteger have. Its usage is quite simple - when you call the constructor BigInteger(int, Random) like this: BigInteger randomBigI...

public class QuickSort { private static int Partition(int[] input, int low, int high) { var pivot = input[high]; var i = low - 1; for (var j = low; j <= high - 1; j++) { if (input[j] <= pivot) { i++; ...

In C, all arguments are passed to functions by value, including structs. For small structs, this is a good thing as it means there is no overhead from accessing the data through a pointer. However, it also makes it very easy to accidentally pass a huge struct resulting in poor performance, particula...

The unary + and - operators are only usable on arithmetic types, therefore if for example one tries to use them on a struct the program will produce a diagnostic eg: struct foo { bool bar; }; void baz(void) { struct foo testStruct; -testStruct; /* This breaks the constraint so mu...

We have a DataListComponent that shows a data we pull from a service. DataListComponent also has a PagerComponent as it's child. PagerComponent creates page number list based on total number of pages it gets from the DataListComponent. PagerComponent also lets the DataListComponent know when user c...
